Oak fire doors
An oak fire door is a fire-resisting core with an oak veneer on the face. The oak does not provide the fire resistance and it does not compromise it; the core and the tested assembly do the work. It exists so a rated door can sit on a landing with unrated oak doors without announcing itself.

The usual reason for buying one is a loft conversion. The job brings a fire door requirement onto a landing that already has four oak doors on it, and a white flush fire door would be the only thing anyone ever looked at.
Two things about oak fire doors surprise people, and both are worth knowing before the delivery arrives.

The veneer is not doing the work
The fire performance comes from the core: a dense, fire-resisting board that is substantially heavier than the hollow or particle core inside a standard internal door. The oak is a face applied to it, chosen for looks.
That weight is the first surprise. A 44mm fire door is a heavy object, it needs three hinges of the correct grade, and hanging one alone is not a sensible plan.
It will not sit flush with your other doors
The second surprise is thickness. A standard internal door is 35mm; an FD30 leaf is normally 44mm. Put them in adjacent openings with the same lining and the fire door sits noticeably proud.
It is not a defect and it cannot be planed away, because thickness is part of what was tested. The fix is at the frame: the fire door needs its own correctly rebated lining, and getting that right is what makes the two doors read as a matched pair from the landing.
Finishing an oak fire door
An unfinished oak fire door still needs finishing, and here the choice of product is not purely cosmetic. Coatings can form part of what was tested, and some finishes — particularly heavy build coatings — fall outside a manufacturer’s stated permitted range.
[VERIFY: manufacturer’s certification and finishing instructions] before choosing an oil, lacquer or paint for a fire door. On an ordinary oak door this would be advice; on a fire door it is a condition of the certification.
